PA STEBOARD-BENDING MACHINE.

Specification of Letters Patent.

Patented March 20, 1906.

Application fi1ed J'un'e 25, 1904- Serial No. 214,133.

To all whom it may concern:

Be it known that I, IRVING L. SHELDON, a citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Pasteboard-Bending skilled in the art, to which it appertains to.

make and use the same.

My invention relates to certain new and useful improvements in a machine of this class which will prepare and flange the top or bottom edges of the sides of a pasteboard box, so that the top or bottom pieces may be quickly and strongly joinedto the sides. It applies more especially to the flanging of the sides of round or oval boxes, such as band'or hat boxes, which require special preparation of the edges before they can be turned in a circle after flanging.

Referring to the accompanying drawings, which form a part of this specification, Figure Iis a side elevation of the improved machine; Fig. 2, an end elevation. Fig. 3 is a section of a box edge prepared by the machine for flanging and turning in a circle. A portion is shown-flanged. Fig. 4 is a plan view. Fig. 5 is a vertical section substantially on line A of Fig. 4, certain portions of the frame and.

shafts being 'cut away to better show the interior mechanism.

Similar reference numerals denote like parts in the several figures of the drawin s.

1 is a tank, preferably-of metal, for hoLding liquid glue, which is kept fluid by the steam: bottom 2, having a steam-supply pipe 3 and drip ipe 4. The tank is supported by frame legs 5. Brackets 6, bolted to its sides, support an operating-table 7 and the end of the driving-shaft 8, journaled in box The shaft is driven. by pulley-wheel 10- 9. from any convenient power. Its other end is journaled in a bar 11, which is supported clear of the operating-table by the subsidiary frames 13 14, which rise from and are secured to the sides-of the metal tank. In frame 14 (see Fig. 2) is journaled a shaft 15 substantially parallel with the driving-shaft. Each of these shafts carries on its end outside of the frames (see Fig. 4, where the frames are shown in section) pulley-Wheels 16 17 of the same diameter, which are belted together by the belt 18, so that they move in unison. Upon the shafts 8 and 15 on thenear outside face'of thearched frames 13 and 14 is placed corresponding gear-wheels 19- 'and' 20. There is also journaled on both frames a lower series of shafts 21 22, (see Figs. 2 and 5,) which have on their ends gearwheels 23 24 of the same diameter and meshing into gear-Wheels 19 20. Thus the belt 18 when driven'by the power-shaft causes all four shafts 8 15 21 22 to move in unison.

Within the frame 13 upon the shafts 8 and 21 is placed a pair of friction-wheels 25 26 (see Fig. 5,) the lower wheel having a raised cutting edge 27- and the upper wheel a corresponding depression for the purpose of scoring a bending-line on the under side of the tion-wheels. Upon shafts 15 and 22 is placed a similar pair of friction-wheels 28 29, which deliver the pasteboard sheet clear of the machine u on the operating-table.

Upon the riving-shaft near its bracketsupport (see Fig. 4) 'is placed a large gearwheel 30, which operates a pinion-gear 31,

.naledat one end ina box 12, sup orted by .the bracket 6, and at its other end in a box below the operating-table. To this shaft is secured a bevel-gear 33, meshing into a com.- panion gear 34, which drives atright angles. the shaft 35, journaled in-boxes 36 37, at tached to the operating-table and parallel with it. The other end of this shaft carries a cutter-head 38, to which is secured the cutter-blade 39, which in its sweep intersects and passes through an opening in the operating-table provided with a plate,40, having a knife-edge corresponding to the cutter edge. 1 About midway of the tank 1 is arranged a wheel 42, driven from a pulley 43 upon the driving-shaft by the belt 44 and at its other end,'within the tank, a glue-wheel 45, which revolves in and raises the liquid glue upon its table, removes any surplus glue. On top of the glue-wheel is arranged a small rollerwheel 47, whichrests upon'it and which is 49 in the bar 11 and made adjustable by the nut 50. There is also arranged upon shaft15 secured to a parallel shaft 32, which is jour shaft 41, journaled in the tank sides for easy removal, having at its outboard end a pulleysurface. A scraper-bar 46, attached to the journaled in an arm 48, carried upon the stud pastebo'ard as it is drawn between the fric- Within frame 14 a flanging-wheel 51, whose purpose will be hereinafter stated.

The operation of the machine is as follows, (see Figs. 4 and 5 2) A sheet of pasteboard being laid u on the operating-table, its edge in contact W1th the guide-piece 52 is moved forward until the friction-wheels 26 grip it. These move it forward, at the same time scoring a bending-line on the under side of the pasteboard sheet, until it encounters the cutter-blade 89, which is revolving through the table edge at any predetermined speed, governed by the arrangement of the gear and pinion wheels 30 and 31, and which blade will cut tapered slots in the edge of the pasteboard sheet, as shown in Fig. 3, at any desired distance apart. The slotted pasteboard then moves forward upon the gluewheel 45 and is pressed down upon it by the roller 47, whereby the lower side of the slotted sections are coated with glue. As the sheet continues" its forward movement these sections encounter the fianging-wheel 51, which bends them down at right angles between itself and the pair of friction-wheels 28 29, which now grip the sheet and deliver it beyond the action of the machine in readiness for the insertion of the top or bottom pieces.

I make no claim to the broad principle of slotting the edge of a sheet of pasteboard, believing that to be in general use. What I claim is the mechanism of a machine by which I score, slot, glue-coat, and flange the edge of a sheet of pasteboard in one continuous operation.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a paper-box machine, in combination, a frame, a tank supported by said frame,

an operating-table supported above said tank, means for moving a sheet of pasteboard along sald table, means for serratlng the edge of said sheet at predetermined distances, means for coating the serrated sections with adhesive matter, and means for bending said sections at right angles to the sheet-surface, substantially as described and shown.

2. In a paper-box machine, in combination, a frame, an operating-table supported by said frame, means for moving a sheet of pasteboard along said table, means for scoring a bending-line on the lower side of said pasteboard sheet, means for dividing the edge of said sheet into sections abutting on said bending-line, and means for bending said sections at right angles to the plane of said sheet, substantially as described and shown.
